This is a very common location to check the state of the deployment. Provided the IDE has deployed successfully, this would be the next place to check. Navigate to the hub URL and scroll down to the History.
This is an example of a successfully completed deployment. When there is an error, the background of the history item is in red. Under the Parameters column is the source details of the webbook. This example is for a GitHub deployment. This address is the GitHub server address and may not be an accepted address if the state of the deployment is 'pending'.
Obtain the log by selecting the contents of the listbox and past it into an editor for easier browsing - the hub refreshes every 30 seconds wiping out your currently scrolled position.
